Precision agriculture merges modern computational technologies such as Artificial Intelligence, Internet of Things, drones, and machine learning to optimize agricultural practices, improve productivity, and ensure sustainability. By enabling data-driven decision-making, it helps to reduce resource waste, enhances soil health, and reduces environmental impact. The synergy between precision agriculture and Climate-Smart Agriculture (CSA) improves resilience against climate change while emphasizing sustainable resource management. Policy support, global policies, and research investments play a significant role in driving adoption and innovation. In this chapter, the author presents key concepts, applications, and future opportunities in precision agriculture, focusing its potential to transform farming, improve food security, and lead to sustainable agricultural development worldwide.
